New, deep, narrow-band images of the Orion nebula obtained
with WFPC2 on the Hubble Space Telescope and the spectra
obtained with the HIRES spectrometer at the Keck Observatory
are presented. The new data reveal many new circumstellar
disks seen in silhouette against the background nebular
light. Deep narrow band \lambda6300 images reveal skins of
glowing [O~I] emission associated with several disks
embedded within bright proplyds. Dozens of stellar jets are
seen to emerge from the protostars embedded in the Orion
Nebula proplyds. Most jets are very compact, one sided
(monopolar), and are sub-arcsecond scale microjets too
small to be seen on ground based images, especially against
the bright background nebular light. Many young stars in the
outskirts of the Nebula are surrounded by large scale bow
shocks facing the core of the Nebula. These structures may
be produced by wide-angle stellar winds interacting with the
outflow of plasma from the Nebula. The largest such
structure is associated with the star LL Orionis. The new
data is combined with older HST images to determine proper
motions of many nebular features. In some cases the Keck
radial velocities then permit determination of spatial
velocities. Most of the bow shaped features exhibit large
proper motions with velocities ranging from 100 to 300 km/s.
The large number of supersonic features provides evidence
that stellar outflows inject large amounts of kinetic energy
into the nebula and may be responsible for generating
chaotic and turbulent motions. Though many outflow sources
are visible stars embedded within the nebula, many others
lie hidden within the dense background molecular cloud.
